The device is arranged below a discharging opening in the lower end of a shredding machine case and is provided with a scrap outward pushing mechanism which runs in an upward inclined mode. And a residual liquid collecting mechanism is arranged below the chip outward pushing mechanism. According to the implementation of the device, residual liquid flowing in dirty scrap steel scraps instantly flows into the residual liquid collecting mechanism below the scrap outward pushing mechanism through the scrap outward pushing mechanism; in the pushing time of the scrap outward pushing mechanism, most of residual liquid remaining on the dirty scrap steel scraps flows into the residual liquid collecting mechanism below the scrap outward pushing mechanism from top to bottom through the scrap outward pushing mechanism; therefore, the residue pouring step in the prior art is replaced by the shredded residual liquid collection assembly line; therefore, the residue pouring time, the residue pouring labor cost, the residue pouring site and the energy consumption of residue pouring equipment can be saved, and the working environment is optimized.

Description

Technical Field

[0001] The utility model relates to the field of smelting recycled steel from dirty scrap steel barrels, in particular to a shredding residual liquid collection line device for dirty scrap steel barrels. Background Art

[0002] The dirty scrap steel drums in this article include: scrapped 200L lubricating oil packaging steel drums, scrapped 200L chemical raw material packaging steel drums, scrapped 20L paint and coating packaging steel drums, etc.

[0003] According to the National List of Hazardous Wastes, the above-mentioned dirty scrap steel barrels basically belong to the category of hazardous waste HW49, with the waste code 900-041-49.

[0004] The reason why the above-mentioned dirty scrap steel barrels are defined as hazardous waste is that the remaining packaging materials inside them are all hazardous wastes.

[0005] In this article, the liquid remaining inside the dirty scrap steel barrel is referred to as residual liquid.

[0006] Because the residual liquid has a certain viscosity, the residual liquid exists in the dirty scrap steel barrel in two forms; one form is the residual liquid accumulated at the bottom of the dirty scrap steel barrel, and the other form is the residual liquid remaining on the wall of the dirty scrap steel barrel.

[0007] According to the latest and most authoritative "T-ZGZS 0302-2020 Group Standard for Recycling of Scrap Steel Drums", the current production line for smelting recycled steel from dirty scrap steel drums in my country consists of the following steps:

[0008] Residue emptying step: The residue emptying step is completed by opening the lid and inverting the dirty scrap steel barrel, or by opening the lid and sucking out the residual liquid to complete the residue emptying process, thereby turning the dirty scrap steel barrel into a residue empty scrap steel barrel; a residue empty scrap steel barrel refers to a scrap steel barrel that has been emptied but the residual liquid has not been completely removed.

[0009] In the above work, whether it is achieved by inverting or by suction, it takes a long time to wait for the residual liquid remaining on the wall of the dirty scrap steel barrel to flow downward.

[0010] Because the lid of the steel barrel is installed close to the top of the side wall of the steel barrel, it is difficult to pour out the residual liquid in the scrap steel barrel even if the lid is opened and turned upside down, because there is a dead angle between the lid and the side wall.

[0011] Shredding step: Use a shredder to shred the scrap steel barrel after the emptying step to turn it into dirty scrap steel debris.

[0012] Cleaning step: the dirty scrap steel fragments that have completed the shredding step are sent to the cleaning machine for cleaning, and the residual liquid on the dirty scrap steel fragments that has not been removed is re-emulsified or dissolved or removed by other cleaning methods to make them relatively clean scrap steel fragments.

[0013] Crushing step: The scrap steel chips that have completed the cleaning step are sent to the crusher for crushing, so that they are transformed into spherical smelting recycled steel with reduced particle size and increased density.

[0014] Magnetic separation step: The spherical smelting recycled steel that has completed the crushing step is subjected to magnetic separation to turn it into spherical smelting recycled steel with higher purity.

[0015] Although the above-mentioned steps are accepted by enterprises that produce recycled steel from scrap steel barrels, their disadvantages are as follows:

[0016] Emptying step: Because there is currently no equipment in my country for automated assembly line operations for the emptying step of scrap steel barrels, this step is mainly performed manually. The disadvantages are: large site area, low work efficiency, long time consumption, high labor costs, poor working environment, easy to pollute the environment due to leakage, and it is difficult to empty it cleanly.

[0017] Shredding step: Due to the problem of incomplete dumping in the dumping step, there is a problem of residual liquid flowing and contamination in the scrap steel barrel during the shredding step after the dumping.

[0018] If the flowing residual liquid is to be collected, there is currently no equipment in my country for automated assembly line operation for residual liquid collection. If manual collection is used, the disadvantages are: low work efficiency, high labor costs, and poor working environment.

[0019] If the discharge port of the shredder chassis is connected vertically to the feed port of the cleaning machine, the disadvantage of residual liquid flow and pollution can be avoided, but the disadvantage is that it not only wastes residual liquid resources, but also further increases the cleaning burden of the cleaning machine. Utility Model Content

[0020] The utility model aims to overcome the shortcomings of the background technology and provide a dirty waste steel barrel shredding residual liquid collection line device which eliminates the residual pouring step and integrates shredding and residual liquid collection.

[0022] A dirty scrap steel barrel shredding residual liquid collection line device includes a shredder, and is characterized in that: a debris outward pushing mechanism that runs upward and tilted is arranged below the discharge port at the lower end of the shredder chassis; and a residual liquid collection mechanism is arranged below the debris outward pushing mechanism.

[0023] The utility model adopting the above technical scheme has the following outstanding effects: the dirty scrap steel fragments after shredding are discharged to the outside world at a high place by the fragment pushing mechanism; during this period, the residual liquid flowing in the dirty scrap steel fragments will instantly flow into the residual liquid collecting mechanism below the fragment pushing mechanism through the fragment pushing mechanism; most of the residual liquid remaining on the dirty scrap steel fragments will also flow from top to bottom through the fragment pushing mechanism into the residual liquid collecting mechanism below the fragment pushing mechanism within the pushing time of the fragment pushing mechanism; thus, the residual discharge step of the prior art is replaced by the shredding residual liquid collection line; thus, not only can the residual discharge time, labor cost and site be saved, the energy consumption of the residual discharge equipment be omitted and the working environment be optimized; the residual liquid resources can also be collected by the assembly line, the working site can be kept clean and the cleaning burden of the cleaning step can be reduced to the maximum extent.

DETAILED DESCRIPTION

[0045] The present invention is further described below by way of examples, the purpose of which is only to provide a better understanding of the present invention. Embodiment 1:

[0046] Device structure embodiment:

[0047] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 ;

[0048] The shredder 1 in this embodiment is a 1200-type double-shaft shredder for shredding dirty scrap steel barrels, and the motors driving the shredder 1 to rotate and work are two 55-kilowatt electric motors.

[0049] The shredder 1 in this embodiment is mainly composed of a shredder bracket, a shredder chassis 101, a shredder feeding hopper 102, two reducers and two motors.

[0050] Two tool drive shafts are installed inside the shredder chassis 101 . The two tool drive shafts are both equipped with shredder knives 103 and bushings. The power input ends of the two tool drive shafts are installed on both sides of the shredder chassis 101 .

[0051] The shredder chassis 101 is installed at the center of the upper end of the bracket, and two motors drive two reducers installed on the shredder bracket at both ends of the shredder chassis 101, and the power output shaft of each reducer is connected to the power input end of the tool drive shaft.

[0052] The upper end of the shredder chassis 101 is the upper feed port of the shredder chassis, and the lower end of the shredder chassis 101 is the lower discharge port of the shredder chassis; the upper feed port of the shredder chassis is connected to the shredder feed hopper 102; the upwardly tilted debris outward pushing mechanism 4 is installed below the lower discharge port of the shredder chassis.

[0053] The dirty scrap steel barrel enters the shredder chassis 101 through the shredder feeding funnel 102 and is cut and shredded by the shredder cutter 103. After being cut and shredded, the dirty scrap steel barrel becomes dirty scrap steel debris mixed with residual liquid.

[0054] Below the discharge port at the lower end of the shredder chassis 101, a debris outward pushing mechanism 4 that runs upward and tilts is provided; below the debris outward pushing mechanism 4, a residual liquid collecting mechanism 5 is provided.

[0055] In this embodiment, the residual liquid receiving port area of ​​the residual liquid collecting mechanism 5 is larger than the residual liquid discharge area of ​​the debris outward pushing mechanism 4 .

[0056] The debris pushing mechanism 4 herein running upwardly tilted is a sorting mechanism for receiving dirty scrap steel debris mixed with residual liquid discharged downwardly from the discharge port at the lower end of the shredder chassis; because the debris pushing mechanism 4 runs upwardly tilted, the dirty scrap steel debris is pushed upward from the bottom to the outside world at a high place, while the residual liquid mixed in the dirty scrap steel debris flows downward from the top to the residual liquid collecting mechanism 5 at a low place under the action of its own gravity.

[0057] The residual liquid collecting mechanism 5 herein is a mechanism for collecting the residual liquid flowing downward from the debris pushing mechanism 4 outwards.

[0058] Based on the above device structure, the technical solution used is: a debris outward pushing mechanism 4 that runs upward and tilted is provided below the discharge port at the lower end of the shredder chassis 101; and a residual liquid collecting mechanism 5 is provided below the debris outward pushing mechanism 4.

[0059] Device working example:

[0060] In this embodiment, the production line for smelting recycled steel from dirty scrap steel barrels is mainly composed of a shredding unit, a sorting unit, a cleaning unit, a crushing unit and a magnetic separation unit.

[0061] The above-mentioned sorting unit is a sorting unit formed by the technical solution of this article and is used to sort dirty scrap steel fragments mixed with residual liquid.

[0062] The technical mission of the sorting unit is to sort the dirty scrap steel fragments mixed with residual liquid, and to separate the residual liquid on the dirty scrap steel fragments as much as possible; to push the dirty scrap steel fragments from bottom to top to the outside world at a high place, and the residual liquid flows from top to bottom to the outside world at a low place under the action of its own gravity.

[0063] In this embodiment, the external environment at the upper part is the cleaning unit, and the external environment at the lower part is the residual liquid collecting mechanism 5.

[0064] The technical problem solved by the utility model is to use a "sorting unit" to replace the "residue dumping step" in the prior art.

[0065] In this embodiment, the dirty scrap steel barrel is a scrapped 200L lubricating oil packaging steel barrel. Since the lubricating oil has a high viscosity, the residual liquid in the steel barrel exists in two typical forms; one form is the residual liquid accumulated at the bottom of the dirty scrap steel barrel, and the other form is the residual liquid remaining on the wall of the dirty scrap steel barrel.

[0066] The dirty scrap steel barrel enters the shredder chassis 101 from the shredder feeding funnel 102 and is cut and shredded by the shredder cutter 103. After being cut and shredded, the dirty scrap steel barrel becomes dirty scrap steel debris mixed with residual liquid and falls on the debris outward pushing mechanism 4.

[0067] During this period, the residual liquid accumulated at the bottom of the dirty scrap steel barrel becomes the residual liquid flowing in the dirty scrap steel fragments, and the residual liquid remaining on the wall of the dirty scrap steel barrel becomes the residual liquid remaining on the dirty scrap steel fragments; during this period, the residual liquid flowing in the dirty scrap steel fragments will instantly flow into the residual liquid collecting mechanism 5 below the debris outward pushing mechanism 4 through the debris outward pushing mechanism 4.

[0068] Most of the residual liquid remaining on the dirty scrap steel chips also flows from top to bottom into the residual liquid collecting mechanism 5 below the chip pushing mechanism 4 through the chip pushing mechanism 4 during the pushing time of the chip pushing mechanism 4.

[0069] The dirty scrap steel fragments mixed with residual liquid mentioned in this article refer to scrap steel fragments contaminated by residual liquid; the scrap steel fragments contaminated by residual liquid exist in two forms, one of which is that residual liquid flows in the dirty scrap steel fragments, and the other form is residual liquid remaining on the dirty scrap steel fragments.

[0070] The size of the dirty scrap steel chips obtained by cutting and shredding is about 50mm*250mm. Since the dirty scrap steel chips of this size are rectangular, they fall on the chip pushing mechanism 4 in a horizontal position. Because their height is only about 50mm, which is only equivalent to one eighteenth of the height of a 200L dirty scrap steel barrel, the falling time of the residual liquid remaining on the dirty scrap steel chips is about 18 times faster than the falling time of the residual liquid remaining on the wall of an inverted 200L dirty scrap steel barrel.

[0071] After the above-mentioned residual liquid separation, the dirty scrap steel fragments obtained are the separated dirty scrap steel fragments.

[0072] Based on the above logic, the longer the running distance of the upward inclined debris pushing mechanism 4, the slower the running speed, and the greater the inclination, the greater the probability that the residual liquid remaining on the dirty scrap steel debris will be sorted out.

[0073] Because the residual liquid collecting mechanism 5 collects residual liquid at any time, all residual liquid collected by the residual liquid collecting mechanism 5 needs to be discharged into the residual liquid storage container in time.

[0074] In a specific implementation, the residual liquid outlet 6 can be connected to the residual liquid storage container inlet through a pipeline; in order to expand its practical performance, a power pump can also be added in the pipeline.

[0075] In this embodiment, the residual liquid outlet 6 is connected to the inlet of the residual liquid storage container through a soft pipeline; the residual liquid storage container is a scrapped 200L lubricant packaging steel barrel; the collected lubricant residual liquid is tested according to the implementation standard of the lubricant, and if all indicators are qualified, the collected lubricant residual liquid can be sold as a lubricant product; if some indicators are unqualified, the collected lubricant residual liquid can be sold as a lubricant raw material or sold as a fuel oil with a lower implementation standard.

[0076] Residual liquid has different properties under different circumstances; if the residual liquid drips into the soil, it is a hazardous waste; if the residual liquid is collected and classified, it is a usable resource.

[0077] The dirty scrap steel barrel in this embodiment is a discarded 200L lubricating oil packaging steel barrel, so the collected residual liquid is a lubricating oil product or a lubricating oil raw material.

[0078] In order to make the collected residual liquid have higher commercial value, it is recommended to classify, shred and sort the dirty scrap steel drums in batches.

[0079] Compared with the prior art, the present technical solution greatly optimizes the working environment because workers do not need to have close and frequent contact with residual liquid.

[0080] Compared with the prior art, the present technical solution greatly reduces the operating site area, so by installing an organic waste gas purifier of the same model, the operating environment can be greatly optimized.

[0081] Compared with the prior art, the technical solution can keep the working site clean because the working site area is greatly reduced and effectively protected.

[0082] Compared with the prior art, the present technical solution can efficiently collect not only the residual liquid accumulated at the bottom of the dirty scrap steel barrel, but also the residual liquid remaining on the dirty scrap steel fragments, so the cleaning burden of the cleaning step can be reduced to the maximum extent.

[0083] Based on the above device structure, the technical effect produced is: the dirty scrap steel fragments after shredding are discharged to the outside world at a high place by the fragment pushing mechanism 4; during this period, the residual liquid flowing in the dirty scrap steel fragments will instantly flow into the residual liquid collecting mechanism 5 below the fragment pushing mechanism 4 through the fragment pushing mechanism 4; most of the residual liquid remaining on the dirty scrap steel fragments also flows from top to bottom through the fragment pushing mechanism 4 into the residual liquid collecting mechanism 5 below the fragment pushing mechanism 4 within the pushing time of the fragment pushing mechanism 4; thus, the residual discharge step of the prior art is replaced by the shredding residual liquid collection line; thereby, not only can the residual discharge time, labor cost and site be saved, the energy consumption of the residual discharge equipment be omitted, and the working environment be optimized; it can also realize the collection of residual liquid resources by the assembly line, keep the working site clean, and minimize the cleaning burden of the cleaning step.

[0084] In order to facilitate visual monitoring of the transport and sorting effect of the dirty scrap steel debris on the debris pushing mechanism 4 and to facilitate the repair and maintenance of the mechanism; the upward inclined debris pushing mechanism 4 is a conveyor belt installed upwardly inclined; the residual liquid collecting mechanism 5 is a residual liquid collecting tank arranged under the conveyor belt.

[0085] The dirty scrap steel barrel enters the shredder case 101 from the shredder feeding funnel 102 and is cut and shredded by the shredder cutter 103. After being cut and shredded, the dirty scrap steel barrel becomes dirty scrap steel debris mixed with residual liquid and falls onto the conveyor belt.

[0086] During this time, the residual liquid flowing in the dirty scrap steel fragments will instantly flow through the conveyor belt into the residual liquid collection tank below the conveyor belt.

[0087] Most of the residual liquid remaining on the dirty scrap steel fragments also flows from top to bottom through the conveyor belt into the residual liquid collection tank below the conveyor belt during the pushing time of the conveyor belt.

[0088] The dirty scrap steel chips that are relatively separated from the residual liquid are discharged to the outside at a high place above the conveying surface of the conveyor belt.

[0089] In order to further improve the conveyor belt's sorting effect on dirty scrap steel chips mixed with residual liquid, the conveyor belt is a mesh perforated conveyor belt or a chain plate conveyor belt with hinge gaps or a chain plate conveyor belt with both perforations and hinge gaps.

[0090] The conveyor belt in this embodiment is a chain plate conveyor belt having both leak holes and hinge gaps.

[0091] Based on the implementation of the above conveyor belt, the residual liquid can not only flow downward along the conveying surface of the conveyor belt, but also flow downward along the leakage holes or hinge gaps of the conveyor belt or the leakage holes and hinge gaps of the conveyor belt, and finally be received by the residual liquid collection tank under the conveyor belt.

[0092] In order to further realize a compact unitized structure of the relevant mechanism; the residual liquid collection trough arranged below the conveyor belt is a three-sided trough body installed upwardly tilted; the three-sided trough body installed upwardly tilted is respectively composed of a trough bottom 501 installed upwardly tilted and three trough edges; the upper side of the trough bottom 501 installed upwardly tilted is below the discharge end of the conveyor belt; the lower side of the trough bottom 501 installed upwardly tilted is below the feed end of the conveyor belt; the left and right sides of the trough bottom 501 installed upwardly tilted are below the left and right sides of the conveyor belt; the trough edges on the three sides are respectively two side edges and a lower end edge 504; the two side edges are respectively the first A side edge 502 and a second side edge 503; the first side edge 502 and the second side edge 503 are respectively connected to the left and right sides of the trough bottom 501 below; the side of the lower end edge 504 is connected to the side of the first side edge 502 and the second side edge 503; a residual liquid outlet 6 for discharging residual liquid outward is provided at the lower end of the three-sided trough body; a conveyor belt for pushing dirty scrap steel debris outward is placed inside the three-sided trough body; the three-sided trough body port below the conveyor belt discharge end is the upper port of the three-sided trough body; the three-sided trough body fixes the feed end of the conveyor belt below the discharge port at the lower end of the shredder chassis 101 through the connecting component 3.

[0093] The three-sided trough body described in this article is a trough body similar to the shape of a dustpan; the three-sided trough body installed at an upward tilt is similar to a dustpan placed at an upward tilt.

[0094] Based on the above device structure, the three-sided trough body and the conveyor belt can be compactly integrated into a unit; the resulting technical effects are: facilitating the collection of residual liquid, saving device materials, saving device space, facilitating unit installation, facilitating unit management, and facilitating unit use.

[0095] In order to further optimize the device structure; at the upper part of the first side 502 and the second side 503 and the lower end 504 of the three-sided trough body, the outer edge of the discharge port at the lower end of the shredder chassis 101 is docked by extending the funnel 2.

[0096] The docking in this article includes fixed docking or movable docking, and the movable docking includes limited docking or insertion docking.

[0097] In this embodiment, the first side edge 502, the second side edge 503 and the upper portion of the lower edge 504 are fixedly docked with the lower portion of the extension funnel 2; the upper end of the extension funnel 2 is movably docked with the outer edge of the discharge port at the lower end of the shredder chassis 101.

[0098] In a specific implementation, the upper end of the extension funnel 2 can also be fixedly connected to the lower end discharge port of the shredder chassis 101, and the upper part of the first side 502, the second side 503 and the lower end 504 can be movably connected to the lower part of the extension funnel 2.

[0099] In a specific implementation, the upper end of the extension funnel 2 can be movably connected to the lower end discharge port of the shredder chassis 101, and the upper part of the first side 502, the second side 503 and the lower end 504 can also be movably connected to the lower part of the extension funnel 2.

[0100] Based on the implementation of this technical solution, the three-sided trough body with a smaller width can collect dirty scrap steel fragments and residual liquid in a larger range, thereby greatly avoiding the leakage of residual liquid. Embodiment 2:

[0101] See attached Figure 5 :

[0102] The only difference between Example 2 and Example 1 is that the residual liquid collection mechanism 5 is composed of a three-sided trough body installed upwardly tilted and a residual liquid storage tank 7 arranged below it; the residual liquid inlet of the residual liquid storage tank 7 is arranged below the residual liquid outlet 6 of the three-sided trough body installed upwardly tilted; the interior of the residual liquid storage tank 7 is connected to the inlet of the discharge pump.

[0103] The residual liquid storage tank 7 in this embodiment is an open four-sided tank body with a relatively large volume and placed horizontally. When the residual liquid in the residual liquid storage tank 7 is about to be full, the residual liquid needs to be discharged to the residual liquid storage container in time.

[0104] Because the residual liquid collecting mechanism 5 collects residual liquid at any time, all residual liquid collected by the residual liquid collecting mechanism 5 needs to be discharged into the residual liquid storage container in time.

[0105] In this embodiment, a submersible discharge pump controlled by a liquid level sensor is installed in the residual liquid storage tank 7, and the outlet of the submersible discharge pump is connected to the inlet of the residual liquid storage container through a soft pipeline. When the residual liquid in the residual liquid storage tank 7 reaches a higher liquid level, the submersible discharge pump will automatically open under the control of the liquid level sensor. When the residual liquid in the residual liquid storage tank 7 reaches a lower liquid level, the submersible discharge pump will automatically close under the control of the liquid level sensor.

[0106] Based on the implementation of this technical solution, the residual liquid collection mechanism 5 can have both the residual liquid collection function and the larger residual liquid storage function; thereby not only saving the labor cost of frequent collection and storage of residual liquid and the energy consumption cost of supporting equipment, but also creating conditions for automatic control. Embodiment 3:

[0107] See attached Figure 6and attached Figure 7 :

[0108] The only difference between Example 3 and Example 1 is that: the three-sided trough body is a three-sided trough body with a notch; the side of the lower end edge 504 is connected to the side of the first side edge 502 and the second side edge 503; the lower side of the lower end edge 504 is spaced apart from the lower side of the trough bottom 501 by more than 10 mm, thereby forming a lower end notch of the three-sided trough body; the lower end notch of the three-sided trough body is the residual liquid outlet 6 for the three-sided trough body to discharge residual liquid to the outside.

[0109] The three-sided trough body with a notch described in this article is a trough body similar to the shape of a dustpan, and a notch is opened below the rear end of the dustpan.

[0110] Based on the implementation of this technical solution, not only the material cost of the three-sided trough body is saved, but also the practical performance of the three-sided trough body is improved; it can be more convenient to discharge the residual liquid in the notched three-sided trough body to the outside, facilitate the visual inspection of the working conditions in the notched three-sided trough body, and facilitate the flushing or cleaning of the sludge in the notched three-sided trough body to the outside.

[0111] Implementation:4:

[0112] See attached Figure 8 and attached Fig. 9 :

[0113] The difference between Example 4 and Example 1 is that: the upwardly inclined debris pushing mechanism 4 is a screw feeder installed upwardly inclined; the shell inlet of the screw feeder is connected to the outer edge of the discharge port at the lower end of the shredder chassis through the extension funnel 2; the shell outlet of the screw feeder is connected to a high place outside; the residual liquid collecting mechanism 5 is the screw feeder shell; and at the lower end of the screw feeder shell, a residual liquid outlet 6 for discharging residual liquid to the outside is installed.

[0114] In this embodiment, the screw conveyor is mainly composed of a screw shaft, a screw conveyor housing and a speed reducer driven by an electric motor; a housing inlet is provided above the lower end of the screw conveyor housing, and a housing outlet is provided below the upper end of the screw conveyor housing; a residual liquid outlet 6 is provided below the lower end of the screw conveyor housing.

[0115] The screw conveyor housing in this embodiment is a steel pipe structure; in a specific implementation, the screw conveyor housing may also be a U-shaped groove structure.

[0116] In this embodiment, the shell inlet of the screw feeder is fixedly connected to the lower part of the extension funnel 2; the upper end of the extension funnel 2 is movably connected to the outer edge of the discharge port at the lower end of the shredder chassis 101.

[0117] In a specific implementation, the upper end of the extension funnel 2 can be fixedly connected to the discharge port at the lower end of the shredder chassis 101, and the shell inlet of the screw feeder can be movably connected to the lower part of the extension funnel 2.

[0118] In a specific implementation, the upper port of the extension funnel 2 can be movably connected to the discharge port at the lower end of the shredder chassis 101, and the shell inlet of the spiral feeder can also be movably connected to the lower part of the extension funnel 2.

[0119] Based on the implementation of this technical solution, not only can the shell of the screw feeder with a smaller diameter collect dirty scrap steel fragments and residual liquid in a larger range, thereby preventing the leakage of residual liquid; it can also find new uses for the shell of the screw feeder, thereby simplifying the device structure, saving device costs, and reducing floor space.

[0120] In order to further optimize the device structure; the residual liquid collection mechanism 5 is composed of a screw feeder housing installed tilted upward and a residual liquid storage tank 7 arranged below it;

[0121] The residual liquid inlet of the residual liquid storage tank 7 is arranged below the residual liquid outlet 6 of the screw feeder housing installed upwardly tilted; the interior of the residual liquid storage tank is communicated with the inlet of the discharge pump.

[0122] The residual liquid storage tank 7 in this embodiment is an open four-sided tank body with a relatively large volume and placed horizontally. When the residual liquid in the residual liquid storage tank 7 is about to be full, the residual liquid needs to be discharged to the residual liquid storage container in time.

[0123] Because the residual liquid collecting mechanism 5 collects residual liquid at any time, all residual liquid collected by the residual liquid collecting mechanism 5 needs to be discharged into the residual liquid storage container in time.

[0124] In this embodiment, a submersible discharge pump controlled by a liquid level sensor is installed in the residual liquid storage tank 7, and the outlet of the submersible discharge pump is connected to the inlet of the residual liquid storage container through a soft pipeline. When the residual liquid in the residual liquid storage tank 7 reaches a higher liquid level, the submersible discharge pump will automatically open under the control of the liquid level sensor. When the residual liquid in the residual liquid storage tank 7 reaches a lower liquid level, the submersible discharge pump will automatically close under the control of the liquid level sensor.

[0125] Based on the implementation of this technical solution, the residual liquid collection mechanism 5 can have both the residual liquid collection function and the larger residual liquid storage function; thereby not only saving the labor cost of frequent collection and storage of residual liquid and the energy consumption cost of supporting equipment, but also creating conditions for automatic control. Embodiment 5:

[0126] See attached Fig.10 and attached Fig.11 :

[0127] The only difference between Example 5 and Example 1, Example 2, Example 3 and Example 4 is that the two sides of the three-sided trough body or the screw feeder with the conveyor belt placed inside and installed upwardly tilted are connected and fixed to the shredder body through a connecting component 3; the connecting component 3 is a hinge connecting component.

[0128] The shredder body described herein refers to the entire shredder 1 .

[0129] The hinge connection assembly in this embodiment is composed of two inner hinge plates, two outer hinge plates, a hinge shaft and other components.

[0130] In this embodiment, the two inner hinge plates are respectively welded to the two sides of the three-sided trough body or the screw feeder, and the two outer hinge plates are respectively welded to the shredder bracket.

[0131] Feed the three-sided trough or screw feeder with two inner hinge plates between the two outer hinge plates, align the hinge holes of the four hinge plates, and insert the hinge pins into the hinge holes of the four hinge plates.

[0132] In this embodiment, an open hinge shaft hole is provided at an appropriate position of the hinge shaft; in order to further improve the practical performance of the hinge shaft, two flat washers are mounted on the hinge shaft outside the two outer hinge plates, and two open hinges are installed on the hinge shaft outside the two flat washers.

[0133] In this embodiment, the weight of the discharge end head of the three-sided trough body or the screw feeder connected to the shredder body by the hinge connection assembly is greater than the weight of the feed end tail; therefore, the use of an unbalanced gravity counterweight can obtain a normal working angle.

[0134] When a three-sided trough or the feed end of a screw feeder is jammed, the feed end tail can be moved down simply by lifting the discharge end head with external force, thereby making it easy to perform on-site maintenance and care on the feed end tail.

[0135] Based on the implementation of this technical solution, the working angles of the three-sided trough or spiral feeder and the shredder 1 can be adjusted at will, and the feeding end of the three-sided trough or spiral feeder with a conveyor belt placed inside installed upwardly can be conveniently inspected, maintained and serviced on site.

[0136] In specific implementations, the three-sided trough or the feed end of the screw feeder is the part with the highest probability of failure.

[0137] The descriptions of the above embodiments are not limitations on the technical solutions of the present utility model. Any equivalent replacement made based on the concept of the present utility model that is merely formal but not substantial should be regarded as within the scope of the technical solutions of the present utility model.
